Introducing the MMS Series Inverter/chargers from Magnum Energy - a new pure sine wave inverter providing a cost effective solution for those with smaller power needs in mobile applications. Versatile, easy-to-use, and lightweight, the MMS Series provides a reliable base for your energy system. The modern, hourglass case, paired with the die cast aluminum base combines form with function, creating an attractive unit that uses its base as a heat sink for superior high temperature operation. The standard 12 Amp transfer relay will pass AC power through the inverter when using shore or generator power. Mount the MMS Series on a shelf, bulkhead, or even upside down. The MMS Series is fan cooled, enabling the unit to work well in confined spaces. If the inverter does exceed its temperature limits, it will automatically shut down and then restart when it cools down. If your battery voltage reaches below 10 VDC or above 15.5 VDC, the MMS Series will automatically shut down. The MMS Series will automatically shut down if its output wattage is exceeded or it detects a short in the wiring, saving the unit from costly damage. The MMS Series comes with an on/off front mounted switch with an easy-to-read LED indicator. The standard battery temp sensor monitors temperatures from 0 - 50° C. Every model comes with built in input and output circuit breakers for ease of installation. The MMS Series is backed by a two-year (24-month) parts and labor warranty.
